The update prompted a sense of relief from many fans.
“Awww... I’ve been wondering where you have been, silently hoping the fellow on the couch had not finally driven you away with his weirdness... looking forward to seeing you again Monday Hilary,” read the most popular comment.
“Was wondering where you were. Glad you’re well. That fella on the couch missed you too but he’ll pretend he didn’t,” wrote another user.
Others speculated the milestone referred to Barry’s husband, Mike Barry’s birthday.
“Welcome back. Hope the mulled wine warmed you up and Mr B had a truly memorable birthday!” said another.
Barry and her husband have been married for more than 26 years.
Before joining Seven Sharp, Barry co-hosted the Breakfast show and was a newsreader for Newshub with Mike McRoberts for several years. She resigned from Newshub in 2016.
